What is the normal working current of white LED lamp?

The working current of LED is only related to the chip. Generally, the rated working current of LED can be 20mA, but it is critical, and it is generally 10~ 15mA. Unless it is a high-power LED, if the estimated current is not large, it can generally be 3 ~ 5 mA. If the current is increased, people can't see the change of brightness.
